Hi all It took some time, but now my testnet seed is fully operational. In fact I've dropped an earlier idea of DNS forwarding and now serving only testnet seed, as it is more important atm than a mainnet one. Testnet seed is available at testnet-seed.alexykot.me. Please check and let me know if

Great, thanks for this contribution! Do you plan to have your seeds reachable on port 53 eventually? Currently bitcoinj cannot deal with nonstandard ports I think. On 05/21/2014 11:23 AM, Alex Kotenko wrote: > okay, I've set it up with bind forwarding requests to two dnsseeds > running on separa

okay, I've set it up with bind forwarding requests to two dnsseeds running on separate ports. Though I see a problem with testnet DNS seed itself. It runs, but somehow it only returns one IP address. Exactly same DNS seeder looking for mainnet nodes is working fine. You can reach seeds through mai

You would set it up as a forwarder, not as a zone transfer to bind. That should proxy the request every time and only cache based on any TTL that’s set in the response. Here’s an example of how it could work: https://planet.jboss.org/post/setting_up_a_forwarding_dns_server_or_dns_proxy_with_isc

Hmm, I've mostly setup what's promised, testing DNS seeds now. There is one problem I see that I can't really solve myself. This dnsseed daemon cannot serve more than one name at once, which means that I cannot serve testnet and mainnet seeds off one daemon instance which means I need to buy two IP
